Acknowledgment. 

The  complete  revision  and  expansion  of  most  of  the  lists 
throughout  the  present  edition  is  exemplified  in  the  very  useful 
combining  of  the  Complete  Type  Collection  List  with  the  oft 
published  Synopsis  of  Dana's  " System  of  Mineralogy."  The 
different  types  and  varieties  thus  follow  each  species  heading 
with  fuller  descriptions  of  the  form  and  physical  characters  of 
each  than  was  practicable  formerly.  A  feature  which  will 
especially  commend  itself  to  mineralogists,  is  the  insertion  in 
proper  position  in  the  systematic  arrangement,  of  all  recently 
discovered  minerals.  This  includes  the  minerals  described  in 
the  new  "Second  Appendix"  to  the  "System,"  access  to  the 
manuscript  being  kindly  given  by  Prof.  Dana.  The  com- 
piler is  especially  indebted  to  Dr.  F.  Ward  for  the  selection  of 
data  from  the  Supplement  and  two  Appendixes,  and  locating 
the  new  minerals;  to  Prof.  Wm.  E.  Ford  for  advice  concerning 
species  of  doubtful  relationship;  to  Prof.  Amos  P.  Brown  for 
suggesting  the  presentation  of  the  hardness  by  group;  and 
finally  to  Prof.  Edward  S.  Dana  and  Messrs.  Wiley  &  Sons 
for  permission  to  reproduce  from  the  "System"  the  numerous 
figures  which  add  so  much  to  the  value  of  the  catalog. 


Rare  Minerals 
In  Commercial  Lots  for  Manufacturers 

Progress  in  metallurgy,  lighting  and  other  special  indus- 
tries in  the  past  decade  has  been  marked  by  a  rapidly  increasing 
use  of  the  rare  metals.  One  of  the  obstacles  which  the  tech- 
nologist faces  is  the  limited  and  irregular  supply  of  raw  material. 
Our  facilities  for  acquiring  these  ores  are  exceptional,  as  we 
employ  traveling  experts  and  are  constantly  receiving  samples 
from  correspondents  throughout  the  world.  The  results  of  thirty- 
three  years  of  wholesale  collecting  affords  a  choice  of  over  two 
thousand  different  varieties  of  minerals,  as  listed  in  the  Com- 
plete Type  Collection,  Part  II.  Specimen  prices  of  several 
hundred  useful  minerals  are  given  in  Part  V,  Economic 
Mineralogy.  The  more  important  are  mentioned  in  the 
Laboratory  List,  Part  VIII,  with  prices  by  weight  for  samples. 
Correspondence  is  solicited  with  consumers  or  experimenters 
desiring  ton  lots.

8  OAK  CHESTS 

The  "  Traveling  Exhibit.' 

An 

Oak  Mineral  Chest 
Is  presented,  if  requested,  with  each  purchase 

of  Hand  size  or  larger  specimens,  totaling  $20.00  or  over.     If 
chest  is  not  requested, 

we  deduct  instead  10  per  cent. 

from  total  price.     These  offers  apply  only  when  all  specimens 
are  kept. 


PLATE  I.    OAK  CHESTS  NOS.  i  AND  2. 

OUR  DISTRIBUTION  of  specimens  (transportation  paid)  takes 
two  forms:— 

FIRST. — Shipments  to  those  who  prefer  to  select  from  the 
specimens  themselves.  Our  knowledge  of  the  needs  of  the 
buyer  are  often  indefinite  and  the  selection  we  make  may  not 
always  accord  with  his  individual  taste.  The  result  is  that 
some  specimens  may  be  returned  at  large  expense  to  the  seller 
and  trouble  to  the  buyer. 

DISCRIMINATING  BUYERS  are  requested  to  give  us  full  advice 
as  to  their  requirements,  thus  permitting  us  to  choose  specimens 
which  may  win  entire  approval. 


OAK  CHESTS  9 

SECOND. — Many  are  able  to  order  from  a  catalog,  and  to 
such  our  material  gives  universal  satisfaction.  Those  ordering 
in  this  direct  way  benefit  by  the  chest  offer,  or  equivalent  10 
per  cent,  allowance,  having  always  the  right  of  prompt  rejection. 

THE  CHESTS  are  iron-bound  and  made  in  the  best  and 
strongest  manner,  of  %  in.  (22  mm.)  first  quality  oak,  antique 
wax  finish.  There  are  three  sizes:— 

No.  i.  Flat  Mineral  Chest.  Measures  inside  23^  x  llH  x 
2^/4  in.  (60x45x7  cm.).  Given  with  not  less  than  $20.00 
worth  of  minerals.  See  upper  chest  in  Plate  I. 

No.  2.  Two- tray  Mineral  Chest,  with  handles.  Measures 
inside  245/3  x  19  x  6^4  in.  (63  x  48^  x  17  cm.).  Given  with  not 
less  than  $35.00  worth  of  minerals.  See  Plate  II,  also  lower 
chest  in  Plate  I. 

No.  3.  Four- tray  Mineral  Chest,  with  handles.  Meas- 
ures inside  24 fi  x  19  x  12%  in.  (63  x  48^  x  32^  cm.).  Given 
with  not  less  than  $50.00  worth  of  minerals. 

THE  OAK  TRAYS  are  of  uniform  size,  measuring  inside  23 %  x 
17^x2^4'  in.  (60x45x7  cm.).  They  are  made  of  %  inch 
(13  mm.)  solid  oak,  with  hand-holes  at  ends,  being  more  con- 
venient to  handle  than  drawers.  Each  oak  ;  ray  is  fitted  with 
25  white  pasteboard  trays  measuring  4^  x  39/16  in.  (12  x  9  cm.). 
Two  of  these  12x9  cm.  pasteboard  trays  are  interchangeable 
with  one  18x12  cm.  tray,  or  one  is  interchangeable  with  two 
9x6  cm.  trays.  Thus  each  oak  tray  holds  from  15  to  50  fine 
pasteboard  trays.  These  are  indispensable  in  keeping  orderly 
arrangement. 

THE  COST  (WHEN  NOT  GIVEN  WITH  SPECIMENS)  delivered  to 
any  address  is,  for  No.  i,  $4.00;  No.  2,  $7.00;  No.  3,  $12.00. 
If  made  singly  by  a  good  cabinet  maker  they  would  cost  double 
these  figures.  Chest  prices  do  not  include  pasteboard  trays. 

If  a  chest  is  not  desired,  then  deduct  10  per  cent,  from 
your  remittance  (of  $20.00  or  over.)  This  is  the  average 
per  "cent,  saved  us  by  avoiding  return  transportation  and 
handling,  when  you  retain  the  entire  lot.  This  allowance  is 
only  on  hand  size  or  larger  specimens  and  only  when  no  speci- 
mens are  returned.

Sample  of  Attached  Label 

On  Hand  Size  Specimen  in  Pasteboard  Tray 

LABELING  is  one  of  the  features  of  our  business  in  which  our 
clients  rely  upon  the  careful  and  conscientious  work  of  the 
trained  mineralogists  in  our  employ.  The  name  of  the  mineral, 
both  species  and  varietal,  and  the  composition  in  chemical 
formula,  are  essential  on  a  reference  specimen.  The  correct 
locality  is  of  importance  and  is  given  especial  attention.  The 
reference  number  in  Dana's  "System  of  Mineralogy"  is  useful 
in  arranging  a  collection. 

The  larger  size  of  the  universal  loose  label  makes  it  more 
easily  read  and  permits  mention  of  the  crystalline  system.  A 
great  disadvantage  is  the  frequent  misplacement  of  the  loose 
labels.  Hence  our  use  of  the  small  attached  label.  Every 
specimen  leaving  our  establishment  has  pasted  on  the  back  one 
of  these  miniature  labels.  The  museum  size  specimens  are  also 
accompanied  by  the  large  Exhibition  Label  when  requested. 


MUSEUM  SPECIMEN  ON  BLOCK 


Museum  Size  Specimens 

Averaging  12x9  cm.  (4%x31/2  in.) 

Weight  averages  about  one  kilogram   (2%  Ibs.  avd.) 

The  illustration  opposite  shows  the  average  size  of  speci- 
mens listed  by  us  for  private  or  public  museums,  for  the  school 
or  college-class  room,  or  for  office  or  laboratory  display,  where 
large  examples  of  showy  appearance  are  desired.  While 
intended  for  glass  cases,  as  shown  in  Plate  VII.,  they  may  be 
held  in  a  drawer  cabinet  fitted  with  pasteboard  trays,  the  drawer 
being  7  cm.  (2%  in.)  deep.  In  preparing  collections  in  the 
museum  size,  especial  attention  is  paid  to  the  shapeliness  of 
each  specimen,  and  to  the  selection  of  bright  colors  and  striking 
crystallizations,  wherever  this  can  be  done  without  impairing 
the  representative  character  of  the  collection. 

Where  specimens  are  desired  for  the  lecture  table  or  passing 
among  the  class,  a  generously  proportioned  specimen  tells  the 
various  properties  and  characteristics  of  the  mineral,  much 
better  than  a  smaller  piece  requiring  longer  study. 

A  PASTEBOARD  TRAY  ACCOMPANIES  EACH  SPECIMEN.  See 
Plate  III. 

OUR  IMPROVED  PASTEBOARD  BLOCK-MOUNT  SUBSTITUTED 
FOR  TRAY,  if  requested,  with  museum  size  specimens.  See 
opposite  page.  It  is  made  of  extra  heavy  pasteboard,  covered 
with  fine  white  paper,  glazed  to  resist  dust.  This  neat  and 
light  paper  block,  affording  a  simple  white  background,  displays 
the  average  specimen  much  more  effectively  than  the  old- 
fashioned  and  sombre  wooden  one.  The  depth  of  the  mount 
is:  Top,  9  cm.  (3^  in.);  base,  13  cm.  (5  in.).  The  slanting 
front  measures  4^  cm.  (ifi  in.).  The  length  is  16  cm.  (6X  m-) 
and  the  height  2^  cm.  (J/%  in.).  Price  for  extra  blocks,  express 
paid,  $8.00  per  100. 

LABELING  is  illustrated  in  Plates  IV.,  V.  and  VI. 

PRICES  for  museum  size  are  double  the  prices  for  hand  size, 
following  mineral  names  in  this  catalog.

PLATE  VII.    COLLECTION  OF  MUSEUM  SIZE  SPECIMENS  WITH  EXHIBITION  LABELS. 


Hand  Size  Specimens 

Averaging  10x7  cm.  (4x2%  in.) 

Average  weight  about  450  grams  (approximately  1  Ib.  avd.) 

"Size  is  a  secondary  factor  in  the  utility  of  a  specimen,  but 
it  is  one  about  which  opinions  vary  greatly.  What  have  you 
found  to  be  the  most  desirable  size  for  mineral  specimens,  in- 
tended for  use  of  students,  and  for  practical  purposes  of  reference?1' 

In  1907  the  above  inquiry  was  addressed  to  teachers  of 
mineralogy  throughout  the  world.  In  nearly  100  replies 
received,  the  average  or  composite  size  preferred  was  10x7  cm. 
(4  x  2$4  in.).  Few  preferred  a  smaller  size  and  some  preferred 
a  size  even  larger.  The  result  of  our  canvass  of  the  opinion  of 
experts  led  us  to  adopt  this  as  our  principal  stock  size,  as  illus- 
trated in  Plate  V. 

THE  CHARACTERISTICS  of  the  mineral  and  its  associations 
are  displayed  far  better  in  this  size  than  is  possible  in  a  fragment. 
The  representative  character  of  the  specimens  in  illustrating 
physical  properties  and  crystallization,  is  considered  of  first 
importance,  but  incidentally  many  of  the  specimens  are  of 
attractive  appearance. 

PRICES  given  after  mineral  names  in  all  collection  lists,  save 
the  crystal  lists,  are  for  standard  Hand  Size  Specimens  aver- 
aging 10  x  7  cm.  (4  x  2^  in.). 

A  PASTEBOARD  TRAY  ACCOMPANIES  EACH  SPECIMEN.  See 
Plates  III  and  V. 

LABELS  are  illustrated  in  Plates  IV  and  V. 
Small  Size  Specimens 

Averaging  7x5  cm.  (2%  x  2  in.) 
Weight  averages  about  225  grams  (Yz  Ib.  avd.) 

If  purchased  in  lots  of  less  than  10  of  one  kind,  the  prices  are  the  same  as 
for  the  hand  size  specimens.  When  purchased  for  classes,  in  lots  of  10  or  more 
pieces  of  one  kind,  the  cost  per  specimen  is  one-half  the  catalogued  prices  for 
hand  size  specimens.  This  includes  delivery  to  any  address,  but  does  not  include 
chests.

Drawer  Cabinets 

Prices  include  crating  and  transportation  to  any  address. 
Made  after  our  own  designs,  based  on  long  experience  in  hand- 
ling specimens,  being  like  cases  recently  manufactured  for  our 
own  equipment.  The  work  of  a  conscientious  cabinet  maker  is 
here  combined  with  the  practical  knowledge  of  the  mineral- 
ogist's requirements. 

FINE  SOLID  MAHOGANY  (%  in.  or  12  mm.)  is  used  for  the 
drawer  fronts  and  for  all  parts  except  the  back  of  the  case, 
sides,  back  and  bottom  of  drawers,  which  are  made  of  5/g  in.  (16 
mm.)  cherry.  Quartered  oak,  at  the  same  cost,  will  be  used 
if  specified  in  order.

Note 

Since  the  appearance  of  our  former  complete  catalog,  an 
improvement  in  the  form  of  label  used  by  us  and  increasing 
care  devoted  to  the  preparation  of  material,  has  resulted  in  a 
general  raising  of  the  already  high  standard  for  which  our  col- 
lections are  noted.  As  in  the  past,  our  aim  is  always  to  select 
the  most  typical  representatives  of  each  mineral  obtainable  in 
the  mines  and  quarries  of  the  world. 

A  price  is  given  opposite  each  specimen  in  the  collection 
lists,  the  figure  quoted  being  for  the  popular  hand  size.  One 
who  does  not  desire  an  entire  set  exactly  as  listed  by  us,  may 
thus  make,  without  correspondence,  an  immediate  selection  of 
any  of  the  specimens  comprising  the  collection,  with  a  knowledge 
of  the  cost  of  each  item.  Selections  may  also  be  made  from  the 
Alphabetical  Price  List  in  Part  III. 

All  but  the  smallest  collections  may  be  purchased  in  the 
catalogued  parts  or  installments,  without  proportionately 
increasing  the  cost.  This  permits  the  gradual  purchase  of  the 
more  expensive  collections,  each  part  filling  important  gaps 
in  the  growing  nucleus  and  not  being  merely  a  detached  section. 
The  ''collection  price"  for  each  set  is  less  than  the  sum  of  the 
individual  values  of  the  specimens  comprising  it.  Our  col- 
lections are  prepared  a  number  at  a  time,  thus  effecting  a 
material  saving  in  labor-cost. 

All  collections  listed,  except  Nos.  lA,  i  and  3 A,  are  ready 
for  shipment  immediately  on  receipt  of  order.

Advanced  Systematic  Collections 

These  are  arranged  according  to  the  generally  accepted 
classification  in  Dana's  " System  of  Mineralogy,"  or  in  the 
" Text-book  of  Mineralogy"  by  the  same  author.  They  can 
be  rearranged  to  accord  with  other  classifications,  as  the  pur- 
chaser may  desire.  The  specimens  have  attached,  labels  and 
numbers  to  correspond  to  numbered  lists. 

Despite  our  exceptional  facilities  for  securing  minerals  through 
our  travelers  or  numerous  correspondents,  and  by  the  purchase 
of  old  collections  replete  with  historic  rarities,  it  requires 
several  years  to  assemble  a  Complete  Type  Collection,  such  as 
is  here  catalogued.  Hence  we  have  always  some  of  these 
advanced  collections  in  course  of  preparation. 

The  descriptions  in  the  list,  made  from  collections  in  stock, 
are  moderate  in  their  indication  of  perfection,  definiteness, 
luster  and  the  characteristics  which  go  to  make  up  good  crystal- 
lizations. No  attempt  is  made  to  indicate  the  beauty  or  attrac- 
tiveness of  the  specimens  beyond  the  bare  statement  of  form 
and  color,  etc.  The  average  standard  of  crystallization  and 
general  excellence,  in  any  collection  delivered  by  us,  will  be  as 
high  as  is  here  indicated. 

It  should  be  kept  in  mind  that  wide  variation  in  types  is  en- 
countered by  all  endeavoring  to  recognize  the  innumerable  forms 
of  the  mineral  kingdom.  The  student  who  has  mastered  a  few 
hundred  specimens  is  often  warned  that  they  represent  but  the 
commoner  types,  and  in  the  field  new  and  unknown  varieties 
confuse  and  puzzle  him  at  every  turn. 

Practice  in  the  examination  of  widely  varying  types  means 
a  fuller  acquaintance  with  minerals  and  increased  power  of 
observation.  Advanced  courses  in  mineralogy  include  constant 
drill  in  the  identification  of  a  large  series  of  minerals  by  sight 
and  by  the  quick  tests  applicable  in  the  field.  Prominent 
teachers  who  are  regular  and  large  buyers  of  minerals,  credit 
their  success  largely  to  these  practical  methods. 

Therefore  as  complete  a  collection  as  possible  should  be 
selected.  The  rarer  specimens,  even  if  not  carefully  studied, 
will  prove  invaluable  for  reference  and  comparison. 


24  ADVANCED  SYSTEMATIC  COLLECTIONS 

No,  1A,     Complete  Type  Collection 

Twenty-five  hundred  museum  size  specimens,  averaging 
12  x  9  cm.  (4^  x  ^y2  in.).  Selected  by  us  from  the  2640 
numbered  and  priced  items  in  the  list. 

Intended  for  individuals  or  institutions  desiring  a  collection, 
which  for  study  or  comparison,  is  fairly  complete  in  the  light  of 
present  knowledge.  Over  six  hundred  distinct  species  are 
represented,  embracing  the  most  important  in  Dana's  "  System," 
including  the  Supplement  and  two  Appendixes. 

The  principal  known  varieties  and  types  of  common  and 
rare  species,  the  crystal  forms  described  in  the  Complete  Crys- 
tal List  and  the  features  of  the  Complete  Physical  Series,  to- 
gether with  the  specimens  comprising  the  large  Economic, 
Chemical  and  Rock-forming  series  catalogued  elsewhere,  all  find 
a  place  in  this  complete  general  collection,  duplication  always 
being  avoided. 

The  multiplication  of  local  examples  is  avoided,  unless  a 
variation  of  type  is  thereby  gained.  The  occurrence  of  the 
commercial  minerals  is  especially  considered  worthy  of  illus- 
tration by  as  many  examples  as  their  variations  demand. 

Our  last  published  catalog  included  a  list  completed  to  1500 
specimens.  In  its  present  enlarged  form,  reaching  over  2500 
specimens,  there  are  comparatively  few  public  or  private  col- 
lections which  excel  it  in  point  of  comprehensiveness  and  gen- 
eral value  for  reference  purposes.

The  University  List,  comprising  the  names  marked  with 
+  or  *,  aims  to  include  such  minerals  as  are  taken  up  in  most 
university  work.  The  300  or  more  distinct  species  emphasized 
by  heavy  type  in  Dana's  "Text  Book  of  Mineralogy,"  are  all 
represented.  Some  of  them  are  quite  rare,  but  are  chemically 
important  and  essential  in  the  illustration  of  a  comprehensive 
and  thorough  course  in  pure  mineralogy.  Examples  are  shown 
of  most  of  the  economic  minerals  which  the  student  or  expert 
may  wish  to  recognize,  because  of  their  commercial  value. 
Numerous  well  known  varieties  which  are  found  with  the  ores 
are  also  worthy  of  representation,  although  not  in  themselves 
valuable. 

Individual  museum  size  specimens  of  most  kinds  may  be 
purchased  at  double  the  hand  size  prices  given  after  each  type. 
The  sum  of  such  individual  values,  in  the  museum  size,  exceeds 
$1000.00.  The  "collection  price,"  including  delivery  to  any

College  Collection.  No  effort  is  spared  in  the  work  of  abridg- 
ment, to  make  this  as  useful  an  advanced  collection  as  the  limited 
number  of  specimens  will  permit.  The  College  List  includes  the 
most  important  minerals  in  Dana's  "Text-book  of  Mineralogy, " 
as  well  as  all  of  the  minerals  contained  in  the  Mining  List  and 
High  School  List.  About  two-thirds  of  the  specimens  are  dis- 
tinct species.  As  in  the  larger  collections,  every  care  is  exer- 
cised that  the  College  Collection  may  be  thoroughly  illustrative,

Remarks  on  the  Synopsis  of 

"The  System  of  Mineralogy" 
Sixth  Edition  with  Appendixes  by  Edward  Salisbury  Dana 

In  this  synopsis  are  inserted  in  proper  position,  new  species 
and  distinct  varieties  or  types  mentioned  in  the  "  Supplement  " 
and  "First  Appendix"  to  the  "System"  and  likewise  the  new 
unpublished  "Second  Appendix"  (1909),  to  the  manu- 
script of  which  access  was  kindly  given.  These  minerals  are 
marked  "S.,f>  "  I."  or  "  II."  in  the  Species  No.  column.  Many 
of  them,  like  some  of  the  "related  compounds"  in  the 
"System,"  are  of  doubtful  position,  owing  to  the  incomplete 
knowledge  concerning  them. 

THE  FIRST  SYNOPSIS  of  Dana's  "System  of  Mineralogy," 
was  published  in  the  " Naturalist's  Agency  Catalogue,"  issued 
by  Dr.  A.  E.  Foote  in  1876.  The  original  "Table  of  Species," 
as  it  was  called,  gave  in  a  condensed  form,  the  physical  and  chem- 
ical characters  of  species,  but  did  not  mention  varieties  or  sub- 
species. In  its  present  form  it  is  a  combination  of  the  last 
published  "Synopsis,"  new  matter  from  the  Appendixes,  and 
our  "Complete  Type  Collection  List." 

THE  NUMBERS  OF  THE  COMPLETE  TYPE  COLLECTION  LIST, 
I  to  2640,  are  given  in  the  first  column. 

COLLECTION  LISTS  are  indicated  in  the  second  column  by 
the  following  signs: — 

Cross  (+)  indicates  the  commonest  or  most  important 
minerals  comprising  the  "College  List"  of  360  specimens. 

Asterisk  (*)  indicates  240  additional  common  or  important 
minerals,  which  with  the  preceding,  comprise  the  "University 
List"  of  600  specimens. 


30  COMPLETE  TYPE  COLLECTION.     DANA'S  SYSTEM 

Circle  (©)  indicates  900  rarer  or  less  important  minerals, 
largely  varieties,  which  with  the  preceding,  comprise  the  '  'Varie- 
tal List"  of  1500  specimens. 

DANA'S  SPECIES  NUMBERS,  i  to  824,  are  given  in  the  third 
column  in  heavy  type. 

THE  SPECIES  NAME  of  each  mineral  is  given  in  heavy  type. 

THE  CHEMICAL  COMPOSITION  is  generally  expressed  by  the 
dualistic  formula,  which  in  the  case  of  complex  compounds, 
often  presents  the  chemical  constitution  more  clearly  than  does 
the  empirical  formula. 

THE  SYSTEM  OF  CRYSTALLIZATION  follows. 

THE  CRYSTAL  FORMS  are  indicated  in  the  commoner  or  the 
best  defined  cases  with  frequent  references  to  the  figures. 

THE  STRUCTURE  is  mentioned  where  of  importance. 

THE  COLOR  is  generally  referred  to  under  each  species. 

HARDNESS  is  broadly  indicated  under  each  group  heading  by 
giving  the  range  from  the  softest  to  the  hardest  species. 

VARIETAL  NAMES,  in  ordinary  type,  are  indented. 

SUBSPECIES  or  " related  compounds,"  also  in  ordinary  type, 
are  in  alignment  with  the  species  names. 

ALTERATIONS  (pseudomorphs)  are  given  only  in  the  com- 
moner types. 

CRYSTAL  FORMS  are  indicated  by  the  letters  used  by  Dana. 
Miller's  symbols  are  shown  in  the  Complete  Crystal  List.  The 
figures,  reproduced  from  the  " System,"  are  idealized  to  show 
the  form  clearly.  In  the  majority  of  cases  the  actual  crystals 
do  not  equal  the  figures  in  the  matter  of  completeness  nor  sym- 
metry; moreover  the  actual  specimens  generally  consist  of 
crystals  on  the  matrix  or  grouped,  unless  marked  "loose." 

SIZE  OF  CRYSTALS  is  given  in  approximate  terms,  as  follows: 
11  Microscopic,"  usually  under  I  mm.  (about  ll^  in.) ;  "minute," 
usually  under  3  mm.  (about  */8  in.);  "small,"  usually  under  i 
cm.  (about  2/s  in.) ;  "  large, "  usually  over  3  cm.  (about  i3/i6  in.) ; 
"very  large,"  usually  over  9  cm.  (about  3^  m-)- 

SIZE  OF  SPECIMENS  listed  at  $0.20  to  $2.50  each,  is  generally 
hand  size,  averaging  10  x  7  cm.  (4  x  2^  in.).  Those  priced 
higher  are  mostly  of  this  size,  but  in  very  many  instances  they 
are  smaller  and  even  insignificant.  They  are,  however,  always 
of  typical  character. 


SINGLE  SPECIMENS  31 

NAMES  OMITTED  in  this  synopsis,  but  mentioned  in  Dana's 
"System,"  "Supplement"  and  two  "Appendixes,"  are  (i). 
Names  rejected  by  Dana.  (2).  Names  given  to  supposed 
minerals  which  have  later  proved  to  be  rocks,  mixtures  or 
highly  impure  substances.  (3).  Some  obscure  varietal  names 
not  prominently  mentioned  by  Dana.  Generally  these  have 
only  local  significance.  (4).  Many  names  of  unimportant 
compounds  of  such  doubtful  character,  that  their  rank  even  as 
varieties,  is  questioned.  (5) .  The  less  frequently  used  synonyms. 

RELATIVE  RARITY  of  good  typical  specimens  of  each  kind, 
is  indicated  by  the  price  following  the  description.  Items  not 
priced,  are,  as  a  class,  rarely  obtainable,  although  there  are 
individual  exceptions  to  the  rule. 

INDEX.  The  position  of  any  mineral  in  the  Synopsis,  may 
be  found  by  referring  to  the  Index  and  Price-List  in  Part  III. 

Single  Specimens 

From  the  following  list,  comprising  all  the  priced  items, 
we  have  on  hand  (outside  of  prepared  collections),  most  of 
those  marked  with  +,  *  or  0,  and  can  fill  orders  for  individual 
specimens. 

Of  the  priced  items  not  so  marked,  many  are  not  on  hand  in 
duplicate.  They  are  generally  quite  rare  and  sometimes  are 
historical  rarities  no  longer  found.  Much  of  this  "floating 
stock,"  comes  to  us  in  one  or  two  specimens  at  a  time,  through 
the  purchase  of  old  collections.  They  are  often  immediately 
reserved  for  our  large  advanced  collections,  in  course  of  pre- 
paration, or  they  are  sent  to  clients  who  place  advance  orders. 

YOUR  DESIDERATA  LIST  should  be  filed  with  us  if  you  want 
rare  minerals.  From  time  to  time,  we  will  submit  for  your 
inspection,  specimens  which  may  "fill  in  the  gaps."

A.  Anhydrous  Silicates 

The  classification  here  adopted  for  the  anhydrous  silicates  can- 
not be  carried  through  strictly,  since  there  are  many  species  which 
do  not  conform  to  any  one  of  the  groups  named,  and  often  the  true 
interpretation  of  the  composition  is  doubtful.  Furthermore,  within 
a  single  group  there  may  be  a  wide  variation  in  the  proportion  of 
the  acidic  element.

PYROXENE  GROUP  107 

2.     Pyroxene  Group.     RSiO3. 

The  orthorhombic,  monoclinic  and  triclinic  species  of  this  group 
are  closely  related  in  optical  and  physical  properties  and  in  angles. 
All  have  a  fundamental  squarish  prism  with  an  angle  of  93°  and  87°, 
with  cleavage  parallel  to  this  prism.  The  metasilicates  of  Ca,  Mg 
and  Fe  In  are  prominent. 

These  species  are  closely  related  to  a  parallel  chemical  series 
formed  by  the  corresponding  orthorhombic,  monoclinic  and  tri- 
clinic members  of  the  Amphibole  Group.  In  several  cases  the  same 
chemical  compound  appears  in  both  groups. 

The  chief  external  distinctions  between  pyroxene  and  amphi- 
bole  proper  are:  prismatic  angle  of  pyroxene  87°  and  93°;  amphi- 
bole  56°  and  124°,  with  more  perfect  prismatic  cleavage.  Pyroxene 
prisms  usually  short  and  often  complex,  massive  forms  mostly  lam- 
ellar or  granular.  Amphibole  prisms  generally  long  and  simple, 
columnar  and  fibrous  types  predominating.

of  basic  igneous  rocks.  They  are  silicates  of  aluminium  with  chiefly 
sodium  and  calcium,  rarely  barium  and  strontium.  The  Zeolites  are 
analogous  to  the  Feldspar  Group,  except  that  the  former  include

Ferrous  iron  gives  to  most  of  these  species  a  green  color.  They 
are  closely  related  to  the  micas  in  their  monoclinic  form,  basal  cleav- 
age and  optical  characters,  but  their  laminae  are  comparatively 
inelastic.  The  Chlorites  are  essentially  silicates  of  aluminium  with 
ferrous  iron  and  magnesium,  and  chemically  combined  water,  man- 
ganese rarely  replacing  the  ferrous  iron.  Tschermak  calls  those 
members  of  the  group  which  occur  in  distinct  crystals  or  plates, 
Orthochlorites;  and  the  fine  scaly  or  indistinctly  fibrous  forms, 
Leptochlorites.

VIII  Hydrocarbon  Compounds 

The  hydrocarbon  compounds  in  general,  with  perhaps  a  few 
exceptions,  are  not  homogeneous  substances,  but  mixtures,  which 
by  the  action  of  solvents  or  by  fractional  distillation  may  be  sepa- 
rated into  two  or  more  component  parts.  Hence,  they  are  not  defi- 
nite mineral  species.  Those  printed  in  capitals  are  indicated  by 
Dana  as  leading  compounds.  A  very  large  number  of  names  of 
related  but  less  important  substances  are  here  omitted.

ABBREVIATIONS.  The  species  numbers  preceding  the  names 
are  those  in  Dana's  "System  of  Mineralogy,"  6th  Ed.  Where 
"r"  or  "n"  follows  the  name  of  a  mineral,  it  is  related  to  or  near 
the  species,  the  number  of  which  precedes  the  indexed  name; 
when  followed  by  "s,"  it  is  a  synonym;  followed  by  "s.  v.," 
"s.n."  or  "s.  r."  it  is  a  synonym  of  a  variety  of  the  species,  or 
a  synonym  of  a  mineral  near  or  related  to  it;  if  followed  by 
"ap."  it  will  be  found  in  the  first  appendix  following  the  species 
number  given.  "H"  designates  Hydrocarbons,  described  at  the 
end  of  the  "System." 

APPROXIMATE  PRICES  are  quoted  on  good  typical  specimens 
of  minerals  ordinarily  in  stock.  A  range  of  price  indicates 
different  types  or  varieties.  Hence  selections  are  best  made 
from  the  preceding  systematic  list,  giving  composition,  crystal- 
lization, structure  and  color,  with  separate  price  for  each  type.

Mining  Sets  of  Industrial  Minerals  and  Ores 
No.  24 A.  School  of  Mines  Collection 

Four  hundred  museum  size  specimens,  averaging  12x9  cm. 
x  $%  in.).  Designed  to  illustrate  as  fully  as  possible  the 
occurrence  of  the  useful  minerals.  The  more  striking  differences 
of  form  are  included,  as  well  as  important  variations  in  quality  of 
ore,  structure,  color  and  mode  of  occurrence. 

The  School  of  Mines  List,  on  the  following  pages,  includes 
all  the  common  economic  minerals,  while  a  few  which  are  rarer 
and  of  less  immediate  commercial  interest,  are  added  because 
valuable  if  found  in  marketable  quantity. 

The  commoner  species  are  shown  in  much  wider  variety 
than  is  possible  in  shorter  collections.  Additional  varieties 
and  types  of  the  commoner  and  more  important  species,  will 
be  found  in  the  list  of  the  Complete  Type  Collection  in  Part  II. 
The  School  of  Mines  Collection  will  serve  every  purpose  of  a  high 
grade  reference  or  working  collection  for  the  mining  man  or 
prospector,  or  for  the  use  of  mining  schools  or  other  institutions 
offering  advanced  courses  in  economic  mineralogy.  Apart 
from  its  utility,  it  makes  an  attractive  and  imposing  display, 
when  properly  cased,  whether  in  the  mining  office  or  public 
museum. 

Individual  museum  specimens  may  be  purchased  at  double 
the  hand  size  prices  in  the  School  of  Mines  List.  The  sum  of 
these  individual  values  in  the  museum  size  is  $1009.20.  The  "col- 
lection price"  for  all  the  specimens  is  $800.00,  delivered  to  any 
address.  This  includes  pasteboard  trays  (or  blocks  if  requested) 
and  two  mahogany  ro-drawer  cabinets.  Without  cabinets, 
10  per  cent.  less. 

PURCHASE  IN  PARTS.  Free  delivery,  with  trays  (or  blocks 
if  requested)  and  one  lo-drawer  cabinet  with  each  part.  With- 
out cabinets,  10  per  cent.  less.

No.  27A,  Mining  Collection 

Two  hundred  museum  size  specimens,  averaging  12  x  9  cm. 
(4K  x  3>^  in.).  The  demand  for  a  reasonably  complete  series 
of  economic  minerals  is  met  by  this  well  arranged  collection. 
As  will  be  seen  in  the  following  "Mining  List,"  which  is  one 
of  the  most  popular  we  publish,  no  attempt  is  made  to  repre- 
sent two  varieties  of  the  same  mineral,  except  with  very  import- 
ant species.  It  contains  a  large  proportion  of  valuable  ores, 
including  practically  all  of  those  mentioned  in  the  principal 
mining  hand-books.  For  the  work  of  the  prospector  or  prac- 
tical man  seeking  acquaintance  with  the  actual  ores  themselves, 
this  collection  meets  every  requirement  possible  within  the

Loose  Crystals  for  Measurement  and  Study 

Advanced   C  ollcctions 

In  the  five  years  since  the  first  publication  of  the  Complete 
Crystal  List,  our  advanced  collections  of  crystals  have  met  with 
a  wider  acceptance  than  was  anticipated.  A  number  of  promi- 
nent teachers  of  crystallography,  well  known  as  writers  on  the 
subject,  after  examining  in  detail  the  Complete  Crystal  Col- 
lection, expressed  surprise  at  finding  such  a  unique  and  excellent 
series  on  sale. 

While  reduced  in  price,  the  advanced  collections  are  super- 
ior to  those  originally  distributed  by  us,  both  in  the  planning 
of  the  list  and  in  the  quality  of  material  furnished.  The  arrange- 
ment and  definitions  in  Dana's  "Text-book  of  Mineralogy" 
have  been  carefully  followed,  making  the  sets  especially  valu- 
able to  those  using  this  work  or  Penfield's  "Determinative 
Mineralogy,' '  most  of  the  crystal  forms  described  therein  being 
included  in  the  collection.  An  arrangement  according  to  any 
other  author,  will,  on  request,  be  prepared  without  extra  cost. 
The  aim  has  been  to  accurately  represent  as  large  a  number  of 
forms  as  possible.  A  duplication  of  any  combination  has  been 
avoided,  even  though  occurring  in  different  minerals.  Variety 
of  form  is  the  primary  object,  while  as  many  species  and  crystal 
groups  have  been  introduced  as  was  practicable.  Out  of 
thirty-two  possible  groups  in  the  six  systems,  only  twenty-three 
are  known  in  nature.  Of  these,  every  one  is  represented.  In 
revising  the  list,  the  Miller  symbols  have  been  added. 

The  individual  crystals  selected  are  the  best  our  extensive 
facilities  afford,  and  have  been  measured  where  necessary. 
They  range  generally  from  I  to  4  cm.  in  length,  and  nearly  all 
are  sufficiently  sharp  and  bright  for  the  reflecting  goniometer. 
The  majority  are  large  enough  for  contact  measurement. 

The  mahogany  cabinets  holding  the  crystals  are  made  ac- 
cording to  our  own  designs,  especially  for  these  collections.  The

4  x  3  cm.  white  glazed  pasteboard  trays  display  the  crystals 
in  an  excellent  manner.  The  crystals  in  each  collection  are 
numbered  to  correspond  to  the  following  list,  besides  having 
on  each  tray  one  of  our  small  printed  labels,  giving  name,  com- 
position and  locality,  as  shown  in  Plate  IV.

Elementary 

No,  77A,     School  Crystal  Set 

The  crystals  selected  for  this  set,  while  essentially  the 
same  as  those  in  the  advanced  collections,  are  generally  over 

I  cm.  in  length,  many  reaching  3  or  4  cm.     Being  intended  for 
elementary  work,  they  are  sufficiently  sharp  for  contact  meas- 
urement, while  many  are  bright  enough  for  the  reflecting  gon- 
iometer.    As   far   as   practicable,    the   commoner   forms   and 
habits,  of  symmetrical  and  model-like  aspect,  have  been  used 
in  planning  the  list  and  selecting  the  actual  specimens. 

On  the  back  of  the  3x4  cm.  tray  accompanying  each 
crystal,  is  pasted  our  miniature  label  giving  name,  composition 
and  locality.  The  light  and  neat  mahogany  cabinet  holding 
the  collection,  is  shown  in  Plate  VIII. 

Single  crystals  are  sold  at  the  prices  in  the  School  Crystal 
List.  They  total  $18.35.  The  ' ' collection  price"  for  the  fifty 
crystals,  with  trays,  in  mahogany  cabinet,  delivered  to  any 
address,  is  $15.00.  Without  cabinet,  10  per  cent.  less.

No.  80.     Lecture  Table  Crystals 

Twenty-five  crystals,  about  10  x  7  cm.  (4  x  2^  in.). 

The  number  of  these  is  limited  by  nature's  supply,  as  few 
minerals  occur  in  crystals  large  enough  to  be  recognized  across 
a  room,  or  even  when  passed  from  hand  to  hand  among  the 
class.  We  have,  however,  arranged  this  incomplete  series, 
embracing  merely  representative  examples  of  the  simpler 
forms.  Some  are  a  little  rough  in  outline,  but  all  are  suffici- 
ently well  defined  to  illustrate  the  form,  and  are  eminently 
adapted  to  this  purpose.  A  number  of  these  minerals  are 
rarely  found  in  such  very  large  crystals,  hence  the  total  of  the 
individual  values  exceeds  $45.00  The  " collection  price,"  de- 
livered to  any  address,  in  trays  and  No.  i  chest,  is  $40.00. 
Without  chest  10  per  cent.  less.  List  sent  on  application.

Physical  Mineralogy 

Series  Illustrating  Hardness,  Structure,  Specific  Gravity, 
Color,  Effect  of  Radium,  etc. 

With  the  exception  of  crystals,  there  are  no  collections  pre- 
pared by  us  upon  which  are  bestowed  a  greater  amount  of  expert 
labor  than  in  the  selection  of  just  the  right  specimens  to  illus- 
trate the  various  physical  characters  of  minerals.  Thus,  in  the 
hardness  sets,  crystals  or  cleavages  are  selected;  under  structure, 
color  and  luster,  a  particular  specimen  from  among  many  of  its 
kind  is  carefully  chosen  with  a  view  to  exactly  illustrating  the 
required  characteristic;  the  specimens  selected  for  specific 
gravity  tests  are  as  pure  and  compact  as  they  are  found  in  nature, 
thus  approximating  the  theoretical  ratio;  the  cleavage  series 
has  been  extended  and  illustrations  of  parting  added.  In 
general  the  definitions  of  Dana  have  been  followed. 

It  should  be  borne  in  mind  that  the  mere  names  of  minerals 
opposite  the  different  terms,  do  not  indicate  the  nicety  of 
variation  shown  by  the  individual  specimens  chosen.  The 
same  species  often  well  represents  different  characters.  As  far 
as  practicable,  however,  the  duplication  of  species  has  been 
avoided. 

The  entire  physical  series,  and  notably  the  color  section, 
makes  one  of  our  most  showy  and  attractive  collections. 

FREE  TRANSPORTATION  to  any  address.

Chemical  Mineralogy 

Specimens  for  Blowpipe   and  Wet  Analysis 

The  material  selected  for  these  collections  is  as  near  chemi- 
cally pure  as  the  minerals  usually  occur  in  nature.  All  are  clean, 
typical  examples  of  distinct  species.  The  list  embraces  those 
commonly  covered  in  an  elementary  course,  and  includes  most 
of  the  minerals  recommended  by  Penfield,  Dana,  Toula,  Platt- 
ner  and  other  writers. 

If  a  more  extended  collection  is  desired,  it  may  be  selected 
from  the  alphabetical  Price  List  in  Part  III.  or  the  School  of 
Mines  List  in  Part  V.  If  the  price  there  given  is  in  any  instance 
for  impure  material,  a  smaller  but  pure  specimen  will  be  sup- 
plied, provided  the  order  mentions  "for  analysis."  If  instead 
of  trimmed  specimens,  a  more  extensive  set  of  pure  lumps  and 
fragments  is' preferred,  they  may  be  purchased  by  weight  from 
the  Laboratory  List,  pages  311  to  3 19. 

No.  119 A.     Series  for  Chemical  Analysis 

One  hundred  museum  size  specimens  of  pure  minerals, 
averaging  12  x  9  cm.  (4^  x  3^  m-)-  The  average  weight  is 
about  1000  grams  (2.2  pounds  avd.),  generally  affording  suf- 
ficient of  each  kind  for  400  to  500  analyses.  Individual  museum 
specimens  may  be  purchased  at  double  the  listed  hand  size 
prices.  The  sum  of  such  individual  values  in  the  museum  size 
is  $129.20.  The  "collection  price"  for  all  the  specimens  is 
$100.00,  delivered  to  any  address.  This  price  includes  paste- 
board trays,  or  blocks  if  requested,  and  two  No.  3  Oak  Chests. 
Without  chests,  10  per  cent.  less.  If  preferred,  an  equal  weight 
of  fragments  in  boxes,  instead  of  trays  or  blocks,  is  sold  in 
chests  at  $100.00.

Laboratory  List 
Minerals  Sold  by  Weight 

TON  LOTS  of  many  rare  minerals  supplied  to  experimenters 
and  manufacturers.  Prices  on  request  if  quantity  desired  is 
stated.  Correspondence  solicited  with  producers  and  consum- 
ers of  rare  ores,  also  colored  semi-precious  stones,  such  as 
Azurite,  Turquois  Matrix,  etc.,  etc. 

QUALITY.  Pieces  usually  consist  of  irregular  lumps  or  frag- 
ments of  about  3  to  9  cm  (i%  to  3>£  in.)  length,  more  or  less. 
Specimens  trimmed  to  uniform  sizes  cost  more.  The  material 
furnished  is  about  as  pure  as  found  in  Nature.  Where  more 
than  5  per  cent,  of  gangue  rock  or  matrix  is  attached,  the  per 
cent,  of  pure  mineral  is  noted. 

FREE  TRANSPORTATION  to  any  address,  with  privilege  of 
returning  any  unsatisfactory  item  at  our  expense. 

EXTRA  STRONG  CARTONS  (double-thick  cylindrical  card- 
board boxes)  hold  each  mineral  conveniently  and  permanently. 

A  MINIMUM  PRICE  of  $0.20  is  charged  for  even  the  small- 
est quantity  of  any  mineral  sold  by  weight. 

i o  TO  50  KG.  samples  of  one  mineral  cost  proportionately  less 
than  listed.  Thus  10  kg.  or  over,  10  per  cent.  less.  50  kg.,  20 
per  cent.  less. 

LESS  THAN  THE  LISTED  QUANTITY  is  charged  at  a  rate  25 
per  cent,  higher  proportionately  than  the  list  price.  Thus 
Manganotantalite  listed  at  $3.00  per  kilo,  costs  $0.37  for  one- 
tenth  kilo;  Glaucodot  at  $4.00  per  kilo  costs  $1.25  for  one- 
quarter  kilo;  Argyrodite  at  $2.50  D.  costs  $0.31  G.;  Beryl  at 
$0.40  K.  costs  $0.20  for  %  K.  (minimum  charge),  etc.
